Seismic imaging of the Waltham Canyon fault, California: comparison of ray‐theoretical and Fresnel volume prestack depth migration
Klaus Bauer, Trond Ryberg, Gary S. Fuis, Stefan Luth
2013, Bulletin of the Seismological Society of America (103) 340-352
Near‐vertical faults can be imaged using reflected refractions identified in controlled‐source seismic data. Often theses phases are observed on a few neighboring shot or receiver gathers, resulting in a low‐fold data set. Imaging can be carried out with Kirchhoff prestack depth migration in which migration noise is suppressed by constructive...

Jennifer E. Swanson, Larissa L. Bailey, Erin L. Muths, W. Chris Funk
2013, Copeia (2013) 670-675
The ability to track individual animals is crucial in many field studies and often requires applying marks to captured individuals. Toe clipping has historically been a standard marking method for wild amphibian populations, but more recent marking methods include visual implant elastomer and photo identification. Unfortunately, few studies have investigated...
